4 Claims.

This invention relates to a door but is also applicable as paneling forWalls and ceilings.

An object of the invention is to provide the planks forming a door panelor the like with parallel grooves in one or both sides thereof, the

planks being connected by dowels which have,

portions thereof extending across the grooves, whereby to exposeportions of the dowels and thus add to the attractiveness of the doorpanel or the like.

A further object is to provide a door of this character having at itsupper edge a strip which is recessed in said edge and strikes againstthe door jamb.

A further object is to provide a door of this character having at itsfree edge a plank which is recessed therein and which provides for theinstallation of a lock.

A further object is to provide a door of this character which will beformed of a few strong, simple and durable parts, which will beinexpensive to manufacture, and which will not easily get out of order.

With the above and other objects in view the invention consists ofcertain novel details of construction and combinations of partshereinafter fully described and claimed, it being understood thatvarious modications may be resorted to within the scope of the appendedclaims Without departing from the spirit or sacrificing any of theadvantages of the invention.

Figure 1 is a front elevation of a door constructed in accordance withthe invention.

Figure 2 is a detail cross sectional view showing contiguous planks ofthe door connected by a dowel pin which is exposed at the parallelgrooves.

Figure 3 is a detail vertical sectional view of the door taken at one ofthe tongue and groove joints of adjoining planks. Y

Figure 4 is a detail cross sectional view of a modified form of door inwhich the grooves are duplicated on both faces of the door and are ofdilerent shape than shown in Figure 2.

Figure 5 is a detail cross sectional view of an- 'other modified form ofdoor in which the grooves are of different shape than shown in Figure 4.

Figure 6 is a detail cross sectional view of another modified door inwhich the grooves are of diierent shape than shown in the other forms ofthe invention.

Referring now to the drawing in which like characters of referencedesignate similar parts in the various views, a door is shown comprisinga plurality of planks III connected together at their longitudinal edgesby joints comprising a tongue II anda groove I2. As is illustrated inFigure 2 the planks are cut away on one face to coact in formingparallel grooves I 3, at the tongue and groove joints. Dowels I4 areengaged transversely through the planks to connect the planks togetherand these dowels extend across the grooves wherebyr to expose portionsI5 of the dowels, these exposed portions alternating with exposedportions of the bottom walls of the grooves I3, see Figure 1. Thisarrangement of dowels having exposed portions extending across thegrooves in the panels provides an artistic ornamental effect ofpanelling in doors, walls, or ceilings, while at the same time thedowels rigidly secure the panels together. Although in Figures l, 2 and3 the dowels are cylindrical the dowels may be of any irregular or othercontour in cross section, and also the grooves may not only be formed onone face of the panelling but may be formed on both faces if desire toenhance the ornamental elfect while still maintaining the rigidity ofthe panel structure by use of the dowels extending transversely throughthe panels and across the grooves.

In Figure 4 is shown a modified form of the invention in which theplanks I6 are butted together at their longitudinal edges and are formedwith V-shaped tongues I I fitting in companion V-shaped grooves I8 inadjoining planks and these butted edges and tongues and grooves may beglued together if desired. In this form of the invention the planks I6are each formed on both faces with semicircular depressions I9 formingparallel grooves when the planks are assembled and rigidly securedtogether by dowels 20 engaged transversely through the planks andextending across the grooves to leave portions of the dowels exposed atthe grooves as heretofore explained.

In Figure 5 is shown another modied form of the invention in which theplanks 2| are formed with abutting longitudinal edges provided withV-shaped tongues 22 received in V-shaped grooves 23 in adjoining planksas heretofore described, but in this form of the invention each plank 2|is provi-ded between its longitudinal edges, on both sides with grooves24 of frustrum shape in cross section through which portions of thedowels 25 which are engaged transversely through the planks, areexposed.

In Figure 6 is shown a still further modified form of the invention inwhich the planks 26 are also provided with butting longitudinal edgeshaving V-shaped tongue and groove joints designated by the numeral 21.In this form of the invention each plank is provided in its oppositefaces with grooves 28 through which the planks securing dowels 29 areengaged, these grooves having inclined walls extending to the exposedportions 30 of the dowels and inwardly of these inclined walls eachgroove is formed substantially rectangular in cross section as shown at3| to provide the flat inner walls of the grooves, hereto indicated bythe numeral l I in Figure 1.

In all forms of the invention the dowels may be formed of diierentmaterial than the planks to enhance the attractiveness of the panelling.

As shown in Figure 1 the door is provided at its upper edge with a Wearstrap 32 which is recessed in the door, since both faces of the door areirrgular due to the formation of the grooves. This strip strikes againstthe top door jamb.

As also shown in Figure 1 the door is provided with a substantiallyrectangular plank 33 which is recessed in the free edge of the door andprovides for the installation of a conventional rock 34..

From the above description it is thought that the construction andoperation of the inventionV Will be fully understood without furtherexplanation.

What is claimed is:

1. Panelling comprising juxtaposed planks provided with parallellongitudinal grooves, and transversely disposed dowels connecting theplanks together and having exposed portions extending across thegrooves.

2. In a door, juxtaposed planks provided with parallel longitudinalgrooves in an exposed side thereof, dowels engaged transversely throughthe planks for connecting the planks together and having exposedportions extending across the grooves.

3. The structure as of claim 1 and in which the planks are provided intheir longitudinal abutting edges with V-shaped tongue and groovejoints.

4. The structure as of claim 1 and in which the planks are connectedtogether at their abuttingr longitudinalv -edges by tongue and groovejoints.
